16.5 X 12 with 39.5x18???

[The Donzi]

Can I run 39.5 x 18 boggers with 15 x 12 rims without worying about popping a bead?

I use the truck for mudriding and grocery hauling.

Heres a pic pre-SOA:

I think it will be fine..
how's your drivetrain going to like 40's? :D

I hope you are getting bigger axles. Boggers will wrap your axles around like a pretzel. Boggers have a very high traction rating. They also take a LOT of power to get to spin. I know guys who have run 35" TSL and spin em no prob in the mud. Then move to 35" boggers and have trouble doing it. So going up to 40" boggers is gona take way bigger axles (D60 front, 14FF rear probabaly) and some way low gears. Like 5.13's or so IMHO.

EDIT: oh yah, about the tires, that should be fine. A 12" rim should pinch a 18" bogger good enough to not pop a beed to easily.

I am planning on upgrading to a 14ff rear and D60 front in the future, I have a set of 4.88 gears and carriers for the D44's.

I got a deal on the boggers, 4 39.5X18 boggers with 80% tread for 550.00 smile.gif

I was originally planning on 38's with my 44's but I couldn't pass up this deal.

I don't like to spin my tires that much anyway, I use 4-lo and try to pick a good line. I usually do pretty good and I don't break anything ;)

Stuka: I am welded front and rear with 3.54 gears, do you think I can handle those tires in 4-Lo? I don't need alot of spin but I do need to be in the power band, do you know the gear reduction of 4-lo on the 1339?

[Stuka]

I think the low range of the QT is 2.57:1, or close to that.

With 39.5" tires and 4.88 gears you would be almost back to stock, just slightly higher. With 3.54 gears you would be WAY higher then stock. Also with having such high gearing with those tires, you will put more stress on the components that are before the axles (u-joints and such). This is because you would have to be using a whole bunch of throttle just to do regular driving.

For offroading I think you wont be very happy at all with 3.54 gears, even in low range. Your gearing is going to be very high.

One thing I would consider is, are you going to put the 4.88's in the axles yourself? If so it may work ok until you get bigger axles so long as you go easy on the skinny pedle. But if your gona pay to have em installed, I say skip that step altogether. And just buy the bigger axles, you will save money in the long run.

your topic says 16.5's.... so are they 15's or 16.5's

16.5's will be fine with the 14ff and D60 but if they are 15's... you will have to run a 2.75" BS 15x12 rim which will require you to grind the calipers on the D60 to fit the rims....

16.5's don;t have a very good safety bead.....so watch them if you air down...

[Stuka]

Ahh yes, good observation Todd. Forgot he will need 16's preferably to use the bigger axles.

Hey Donzi,
Where do you live in New Orleans. I am originally from there, and had to come to the mountains to find decent wheelin. Just wondering where your favorite spots for wheelin are? I am headin down that way sometime this summer.

RB The tires are 16.5 , so I won't need to grind the calipers.

FYR WOOD: I live in uptown, Napoleon and Claiborne area. I ride with a group of guys in the area. We mainly go to the spillway, but sometimes we go to Holly beach, Gilmer TX, Kisatchie Natl. forest.

Our club site is www.2bbdelta.org (http://www.2bbdelta.org) I am the only FSJ so I'll be easy to find in the pics..

Let me know if you come in town and want to go wheeling, I'm always up for a little mud and guts smile.gif

Donzi,

You mentioned 15x12's... if the tires are 16.5's you need to get 16.5" rims... but you know this....

16.5's are notorious for blowing beads when you air them down... they have a small safety bead.... just be careful

[The Donzi]

RB, oops !! I meant to say 16.5 rim. Sorry about the confusion. I decided to pass on the tires anyway. I knew about the 16.5 rim but I wasn't aware of the safety bead problem. I will be wheeling my truck pretty hard and I don't want to risk popping a bead. I am also not really wanting to spend the $$ for beadlocks.

Thanks for all the info guys, I learned a few new things today ;)

[River Beast]

figured it was a typo..... ;)

[orangecherokee]

WOAH WOAH WOAH, are you saying that you can't run a 15" wheel on a 14FF or a d60 due to the caliper clearance??

[River Beast]

yes//// you must clearance the D60 calipers and run a 2.5" BS on the 15" wheel to fit....

Read this post....

well this just chaps my ARSE!!!!! i just bought my new 37 MTRs and they are 15". :mad: :mad: :mad: now what do i do??? this just kills a perfectly good day

[River Beast]

HAHAHAHA!!! I'm not laughing at you .. laughing WITH you.... I have my 38's with less than 1500 miles....yep they are 15's... sitting right next to them are my new 36's.... I feel your pain....

[Stuka]

orange: if they arent mounted can you send them back? Or sell them to oneof the local yota guys. as they always run stock axles with 15's.

[orangecherokee]

contrary to what most folks think..i'm gonna keep them and run them on 15" wheels. i've done some research and i think i can pull it off. it's gonna be a long time before it hits the road again so we'll see when the time draws near.

[rockjeep44]

You can pull it off man, it's not as big of a deal as it sounds. Where's that grinder?
